The stack of shelves (The top Left) would be the most reasonable answer! The reason why I think this is because, muscle tissue has many layers to it. Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. ... Striated or skeletal muscle only contracts voluntarily, upon influence of the central nervous system
I hope this helped you out, a little!
